The embodiment provides a water-vapor separation box, which is matched with a water dispenser and used for guiding out water heated by a heating pipe 400 for a user to take. Referring to fig. 1 and 11, the water-vapor separation cartridge comprises a cartridge body 100, a water inlet pipe 300 and a water outlet pipe 200, wherein the cartridge body 100 is provided with an inner chamber 101, an air outlet 102 communicated with the inner chamber 101 is arranged on the top surface of the cartridge body 100, a water inlet 103 and a water outlet communicated with the inner chamber 101 are respectively arranged at two opposite ends of the bottom surface of the cartridge body 100, the water inlet pipe 300 is communicated with the water inlet 103, and the water outlet pipe 200 is communicated with the water outlet.

Wherein, the box body 100 is provided with a converging structure for converging the water entering the inner chamber 101 from the water inlet pipe 300 at one side far away from the water outlet; the water outlet comprises a first water outlet 104 and a second water outlet 105, the water outlet pipe 200 comprises a first flow passage communicated with the first water outlet 104 and a second flow passage communicated with the second water outlet 105, and the first flow passage and the second flow passage are communicated in front of the outlet of the water outlet pipe 200; the water collected by the collection structure can flow out through the first flow channel or respectively enter the first flow channel and the second flow channel and then flow out after being combined before the outlet of the water outlet pipe 200. Specifically, a first baffle 106 is arranged between the first water outlet 104 and the second water outlet 105, and the first baffle 106 is higher than the first water outlet 104; when the water level in the inner chamber 101 is not higher than the first baffle 106, water flows out from the first water outlet 104, and when the water level in the inner chamber 101 is higher than the first baffle 106, water flows out from both the first water outlet 104 and the second water outlet 105.

When a user takes hot water, the water in the heating pipe 400 enters the water-steam separation box upwards, the water flows into the inner chamber 101, is converged at one side of the inner chamber 101 away from the water outlet under the action of the converging structure, and then flows out to the water outlet, and at the same time, the water vapor moves upwards and is discharged from the air outlet 102 at the top of the box body 100. When the water flow is small, for example, a user takes high-temperature water, the water level of the inner chamber 101 does not exceed the first baffle 106, and the water flow flows out from the first water outlet 104 through the first flow channel; when the water flow is large, for example, when a user takes warm water or warm water, the water level of the inner chamber 101 exceeds the first baffle 106, the water flows out of the first water outlet 104 through the first flow channel, and flows out of the second water outlet 105 through the second flow channel by bypassing the first baffle 106, and as the outlet of the first flow channel is arranged in the second flow channel, the water flow from the first flow channel can flow out after being converged with the water flow of the second flow channel, and the water flow from the view angle of the user is a water flow, so that the split water flow does not appear, and the water shape is good. The length of the water flow from the water inlet to the water outlet is increased due to the arrangement of the converging structure, so that gas-liquid separation is facilitated, and stable water flow is formed by converging at the water outlet. The convergence structure can converge the low-flow water flow and then discharge the water flow, so that the condition that the water outlet is intermittent when the water flow is small is avoided, the water outlet is ensured to be continuous and stable, and the user experience is improved.

Referring to fig. 5, the water outlet pipe 200 may include an outer pipe 201 and an inner pipe 202, the outer pipe 201 has a water outlet channel 203 and a buffer cavity 204, the inner pipe 202 is disposed in the water outlet channel 203, an inlet of the inner pipe 202 is communicated with the first water outlet 104, an outlet of the inner pipe 202 extends to the vicinity of the outlet of the water outlet channel 203, an overflow gap 205 exists between an outer wall of the inner pipe 202 and an inner wall of the water outlet channel 203, and the buffer cavity 204 is communicated with the second water outlet 105 and the overflow gap 205. The inner tube 202 defines a first flow path, and the buffer chamber 204 and the flow gap 205 form a second flow path. The outlet of the inner tube 202 is located within the drain channel 203, and the spacing between the outlet of the inner tube 202 and the outlet of the drain channel 203 is no more than 0.5mm. The outlet of the inner pipe 202 is arranged in the sewer 203, so that the water flows flowing out of the first flow channel and the second flow channel can be converged before the water flows out of the outlet of the sewer 203, and the water is ensured to be attractive in appearance; the space between the outlet of the inner pipe 202 and the outlet of the water outlet channel 203 is reduced, so that the water flowing out of the inner pipe 202 can be prevented from splashing and branching due to the water flowing out of the inner pipe 202 beating the inner wall of the outer pipe 201.

Specifically, the first baffle 106 has a rear blocking portion 107 near the second water outlet 105, and the rear blocking portion 107 is located above the buffer cavity 204 or enters the buffer cavity 204. A second baffle 206 is arranged between the drain channel 203 and the buffer cavity 204, a through-flow port 207 is formed between the rear blocking part 107 and the second baffle 206, and water in the buffer cavity 204 can pass over the second baffle 206 from the through-flow port 207 and enter the through-flow gap 205.

The inner wall of the outer tube 201 is provided with a limit structure which positions the lower portion of the inner tube 202 at the center of the cross section of the drain passage 203. In one possible implementation, the limiting structure may include a step provided on an inner wall of the outer tube 201, the step supporting a lower end of the inner tube 202, the inner tube 202 and the step having an overflow gap therebetween, and water passing over the second baffle 206 passes through the overflow gap and merges with water flowing out of the inner tube 202. In another possible implementation, as shown in fig. 5-6, the limiting structure may include a plurality of limiting ribs 208 spaced on the inner wall of the outer tube 201, each limiting rib 208 being distributed along the long axis of the outer tube 201, and a flow passage being formed between adjacent limiting ribs 208, the limiting ribs 208 abutting against the outer wall of the inner tube 202, and water flowing from the inner tube 202 merging after passing through the flow passage by the second baffle 206.

With continued reference to fig. 5, the lowest water level at the highest position on the inner tube 202 is the first critical water level 209, and the highest water level at the highest position on the inner tube 202 is the second critical water level 210. The first critical water level 209 is higher than the first water outlet 104, and the highest position on the first baffle 106 is higher than the second critical water level 210. Because the higher the water taking temperature of the water dispenser is, the smaller the instantaneous water quantity heated by the heating pipe 400 is, and a continuously and smoothly communicated waterway cannot be formed during water outlet, the phenomenon that the water outlet is intermittent and the water shape is unstable when the water dispenser takes high temperature can be caused. To address this phenomenon, the present embodiment constructs siphoning away from the necessary structural conditions, utilizing the siphon principle to assist in continuous launch. In fig. 5, when the water level at the first water outlet 104 is higher than the first critical water level 209, a pressure difference is formed between the first water outlet 104 and the first critical water level 209, so that the water flow at the first outlet can continuously flow downwards by the pressure difference to form continuous water outlet.

With continued reference to fig. 5, the first flow channel is provided with a first water storage area 211, and the second flow channel is provided with a second water storage area 212; when the water supply to the water inlet 103 is stopped, the inner chamber 101 stops the water supply to the first flow passage and/or the second flow passage. When the inner chamber 101 stops water supply to the first flow passage, the first water storage area 211 is filled with water to block outside air from entering the inner chamber 101 from the first flow passage; when the water supply to the second flow passage is stopped in the inner chamber 101, the second water storage area 212 is filled with water to block the outside air from entering the inner chamber 101 from the second flow passage. Wherein, a pipe section between an inlet on the inner pipe 202 and the first critical water level 209 forms a first water storage area 211. The buffer cavity 204 forms the second water storage area 212, and the highest liquid level of the buffer cavity 204 is equal to or higher than the lower end surface of the rear side blocking part 107, so that when the buffer cavity 204 is full of water, no pore exists between the rear side blocking part 107 and the water in the buffer cavity 204, external air can be prevented from entering the inner chamber 101, bacteria breeding in the inner chamber 101 is inhibited, and water and steam separation box water outlet is cleaner and sanitary.
